Abstract
Organic materials suitable for application in electronics (e.g., thin film transistors and) and optoelectronics (e.g., light emitting diodes) have received increasing attention during the past years. Such new compounds are not designed to replace the existing technology where speed and stability under extreme conditions are vital. These compounds could be potentially used for applications that require short-term use and large- scale manufacture. Of great interest as novel materials are substituted pnetacenediquinones for optoelectronics applications, substituted pentacenes for thin film transistors and indenofluorene derivatives for applications in light-emitting diodes. Pentacenediquinones are compounds that contain five aromatic rings in a row and two quinoid moieties in their structure. Pentacenediquinones can be easily reduced electrochemically to the corresponding semiquinone (radical anion). The semiquinone displays absorbance in the near-infrared (NIR) region, between 1300 and 1500 nm.1'2 By introduction of various substituents on the two "outside" aromatic rings (figure 1), the semiquinones of substituted pentacenediquinones offer a possibility to fine tune the MR activity in the three telecom windows: 1550, 1310 and 880 nm.
